Robot Damashii: Code Geass - Zangetsu

The Zangetsu (斬月 Zangetsu, lit. Slashing Moon) is a eighth generation Knightmare Frame constructed for Kyoshiro Tohdoh's personal use. It bears great resemblance to his old customized Gekka, retaining the same paint-job, shoulder armor and the hair-like attachments. Its performance is well above a standard Gekka however, it is capable of matching some of the more advanced Britannian Knightmares.

While it carries the same single Slash Harken and Seidoutou (制動刀 Seidoutou, lit. "Brake Sword") as the Gekka, it also implements some new weaponry, namely a pair of chest-hidden machine cannons and Radiant Wave Shielding System. These new technologies would be latter incorporated into the Akatsuki Command Model Zikisan. It can also make use of the same Air Glide Wing/Missile Launcher combo unit as the Akatsuki. In such occasions, it is referred as the Type-04/F1C Zangetsu Flight-Enabled Version

The Zangetsu makes its first appearance during the kidnapping of Empress Tianzi fighting against Suzaku's Lancelot Conquista. It shows most of its new features against him, throwing him off guard, but later on recovers. It makes its final appearance during the Second Assault on Tokyo Settlement. The Zangetsu is badly damaged when Lelouch vi Britannia sets off the Sakuradite in Mount Fuji to destroy a large portion of the Black Knights' forces, but Tohdoh continues to fight until his machine is finally destroyed in combat with Suzaku Kururugi and his Lancelot Albion.
